ROLLER-SKATE.

Specification of Iietters Patent.

Patented Nov. 7, 1911.

Application led June 26, 19111. Serial No. 635,394.

Be it known that L'HENRYNANNENHoRn, citizen of the United States, residing at C111- cago, 'in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Roller-Skates; and I do herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thel same."

This invention has for its object to provide an improvement in roller skates.

The invention consists in the features of construction and combinations of parts of the skate hereinafter fully 'described and claimed.

In the accompanying drawings illustrating a' suitable embodiment of the invention:

vFigure -1'-, is a side elevation of a roller skate constructed Vin accordance with my invention. Fig. -2- is a bottom plan view o 'f the same. Fig. -3- is a central vertical longitudinal section of the same on the line 3 3 of Fig. 2-. Fig. -4- is a vertical transverse section of the same on the line 4-4 of Fig. -l-. Fig. -5-lis a fragmentary detail central longitudinal section of the same showing mechanism for converting reciprocal movement of the foot' plate into rotary motion of one of the front rollers of the skate. Fig. 6 is a fragmentary detail section showing theconnection of a shaft wit h a threaded member for rotating said shaft in one direction. Fig. -7-

is a fragmentary detail transverse section on the line 7-7 of Fig. -5-. Fig. -8-

is a fragmentary detail perspective View of one end of the shaft. Fig.` -9- is a fragmentary detail horizontal section on the line Fig. l0- is a vertical transverse section on the line 10-10 floor at each stroke of the'foot of the wearer` -whereby greater speed in skating may e attain The mechanism andwill now be described.

The skate comprises a carriage consistingl ofthe plate 1 which is supported upon a nluralityof caster wheels 2, 3, 4 and 5, the latter being rotatably mounted on the axles 'vand7 suitably mounted upon said plate l adjacent the respective ends thereof by means Aof the flanged plates 8 and 9 respectively. The said Aplate 1 is provided adjacent its rear end with a pair of parallel opposed standrds 10 which are spanned by bolts 11 and 12, each of which carries a rotatable sleeve 13. A similar pair of opposed standards 14 is mounted upon the forward end portion of said plated, said standards being similarly spanned by bolts 15 andv 16 carrying rotatable sleeves 17, the lat-ter being dis osed at a higher elevation relatively to the horizontal plane of the plate 1 than are the bolts 11 and 12 of the standards 10.

18. The s aid'plate- 19 is supported upon the' sleeves or rollers 13 and 17 mounted., upon the bolts -12 and 16 respectively, and is reciprocally movable relatively to the plate 1. Helical tension springs V24 serve .to'maintain' the said plate 19 normally at the rearward limit of its movement relatively to the plate l 1, and, owing to the angular disposition of said plate 19 relatively to the;l plate 1, the

weight of the wearer of the skate will serve to cause said plate 19 to normally moveto the rearward limit of its movement by the gravity pressure imparted theretol TheJ plate 1 is provided in its forward na portion .with an openingA through'.whi'ch a spur pinion 25 and bevel pinion '26, respectively, are' adapted to project, the latterbe-4 ing rigid with a sleeve 27 mounted upon a t shaft or pin. 28 journaled at its ends in the vertical arms 29 of a U-shaped lmember-'30v secured at one endto the lower face of the plate 1 by means of a flange 3 1 and .bolt 32,

and at'its other end to -thetop face of said. plate 1 byi'neans ofthe flange 3,3'projecting through r'said'opeliing therein', f Rotatably mounted u on 'a stud 34"' carried by' said illustrated in the accompanying drawings is adapted t'o carry. outthe object off the'invention plate 14 an disposed in-verticalalinement with the axle 6 'is'a' bevel .gear 35 which meshes with said bevelpinion 26` and with a bevel pinion 36-rigid lwith the caster wheel 4. The said spur pinion 25 meshes with a .leeve fit) is contained i.

The depth of the enlarged portion of eeitl opening 46 and the length of the retliieecl enel portion 43 ot the shaft are respectively suoli es to permit Selci Steeve Ll() e limited longitudinal movement relative to the shaft snliieient to permit the projections l5 to be completely ivithrlrziivn from seid slot l? `Whereupon seid Sleeve el@ will be rotatable relatively to eeirl Slui'lit 3S and vice verse.

Such rotary move nient of the Sluiiiit will be imparted vto tlne caster wheel et through the internietliecy of :anni geur trziin heretofore described, thus rototing Sziitl roller it greater speed than Seid simil. 38, ivill be obvions, :inrl' et greater Speed thun Seid roller ivonltl ordinarily be rotated by contact with the floor :intl movement by the lootot the wearer on the floor, the speed oit travel of the skate on the lloor turing the primary stroke of the toot of the wearer thereof being thus accelerated enel enabling the wearer to :ittni n :i greater Speed in skating. The seid gear trein may obviously be changed and varied to import any desired relative number of rotation@ to the caster Wheel relatively to the Shaft 238 Within certain limits, es will be obvious.

After giving the primary impetus to the slotte by movement of the plete 18 relativelyT to the plete l in one direction e grudunvl reverse movement of the former rehitivelv to the latter Will take pince owing to thi; tension exerted uponitlie plete 18 by the Springs Q42 incl t'urtlrer by the action of gravity es heretofore describedv So that While e.. ropicl relative longitudinal movement of the plates l and. 18 takes place es the :toot ot the iv tirer of the Skate is ploeeil` upon the floor n. gradual reverse movement of Seid plates relatively to each other tahoey pince during the balance of the .stroke .rliereby the seid platee :ire returned to their normal relative positions preparatory to making the Y L Y t next stroke. le ivnl4 be noted that ne the Sleeve il moves rearwardly relatively to the -shzitt 38 the sleeve i0 will else be prinmrily moved rearwardly so es to ilisengege the projections l5 from the slot l? zitter which seid sleeve el() will rotate relatively to the sleeve Lll and slinrlits 38 in the opposite direction Without electing zi .free rotation of seid Shaft (lue to its gearing' with the roller il.
